YOUR HAIR IS: LOW POROSITY.
Having low porosity hair means that your hair cuticles are tightly bound and lay flat, making it increasingly difficult for moisture to enter into your hair shaft. However, once the moisture is in the hair shaft, it is difficult to leave. If you're low porosity, you're probably prone to build up. Consider heavy products sparingly or add water to them to thin them out. Use lighter products such as water based leave in conditioners and gels to keep your hair from getting limp. Products that are too heavy and used in excess, can weigh your hair down. If moisture is an issue, consider applying heat to your hair while you deep condition so that your hair shaft will more easily open up.
YOUR HAIR IS: HIGH POROSITY
High porosity means that you have openings or gaps in your hair cuticle which allow moisture to enter and exit your hair shaft easily. High porosity can be caused by heat damage or chemical damage to hair, but many are born with high porosity. If you are high porosity, your hair benefits from a lot of moisture. Your hair is vulnerable to damage, so handle with care. Protein treatments once a month or every other month can be helpful in strenghthening your hair. Deep condition your hair at least once a week. Using cool water to rinse out your conditioner will help close your hair cuticle to seal in moisture. Be sure to use thick-consistency, creamy products to help give your hair sheen and lock in moisture.
YOUR HAIR IS: NORMAL POROSITY
YOU ARE HAIR GOALS! Normal porosity doesn't require much maintenance, this is because unlike low or high porosity, your hair cuticle layer is looser. This allows moisture in without allowing too much to escape. If you have normal porosity your hair is typically healthy and easy to manage. You may want to alternate co-wash and low-poo for balance. Deep condition with protein conditioners occasionally.
